I have set it up with the battery, uSD card, GPS module. It&rsquo;s successfully logs the data to the uSD card, however the reading I got from the accelerometer were very strange, the values for 2 of the axes are at about 65534 at the same time, which sounds very wrong, since the device is motionless on my desk.<br/>

Are you trying to log GPS at 10 hz? The default code comes configured to work with an EM408 GPS module, and this module isn&rsquo;t capable of logging anything faster than 1 hz. There are modules that we have that can reach 10 hz though, I like the Locosys GPS module. However the GPS libraries would have to be modified to work with this module.</p>fabi on GPS-08755 - Package Trackerfabiurn:uuid:94ee5ee1-a621-8640-99c7-53097e674f232009-07-28T07:06:23-06:00<p>When you &lsquo;//&rsquo; the line 331 in the main_v1-4 the tracker will not go to sleep.<br/>

fabian</p>zagGrad on GPS-08755 - Package TrackerzagGradurn:uuid:b5033648-b00c-8d0f-7291-5e04a60284c62009-06-11T09:13:47-06:00<p>Hopefully you already understand that you&rsquo;ll have to change the firmware and recompile. It&rsquo;s actually very easy to change this value in the code though! I&rsquo;m assuming you&rsquo;re using the latest v1.4 Package Tracker code. In the v1.4 folder, open main_v1-4.c. On line 116, in the main() function, there&rsquo;s a function call:<br/>
WriteLis302Register(FF_WU_THS_1, 55);//Set Accelerometer Threshold to ~1g.<br/>
This is the line that sets the freefall threshold. According to the datasheet for the LIS302 accelerometer, there is 18mg/digit in 4g mode (which is the current configuration). So the default threshold of 55 is 990 mg (55*18=990).<br/>
If you want to change the free fall value, just change the 55 in this line of code to your desired value. Keep in mind, though, that you&rsquo;re limited to 7 bits as the 8th bit has an alternate purpose in the FF_WU_THS register. (i.e. don&rsquo;t set your value higher than 127).</p>fabi on GPS-08755 - Package Trackerfabiurn:uuid:31a09f41-51c3-11f2-1f19-62319bd630942009-06-11T05:22:56-06:00<p>Hi,<br/>

A new version of firmware is available for the package tracker. The improvements are now listed in the product description. If you&rsquo;d like to upgrade your Package Tracker to the new firmware, simply download the Firmwarev1.4 folder from the Documents section of the product description above. Once you&rsquo;ve downloaded and unzipped the folder, open the v1.4 folder inside the downloaded folder. Copy the FW.SFE file onto the Package Tracker and then just unplug the USB cable. Once the Package Tracker is restarted the new firmware will be loaded and start running.<br/>
Good luck, and let us know if you have any questions!</p>zagGrad on GPS-08755 - Package TrackerzagGradurn:uuid:b8e81e65-4a2d-f649-fefe-6beb0e6d71b62009-03-20T08:46:50-06:00<p>Well, the USB hardware is designed according to the ARM datasheet. In the firmware, the main_msc and supporting libraries allow for the USB Mass Storage. You can view these libraries by downloading the source code in the product description if you&rsquo;d like.</p>reza on GPS-08755 - Package Trackerrezaurn:uuid:b695ea38-e949-65bb-e31a-122a6c2c16a52009-03-19T14:31:18-06:00<p>what part of the hardware or firmware allows the device to appear as a mass storage device via usb?</p>MAL on GPS-08755 - Package TrackerMALurn:uuid:054b82ff-dd00-58f5-991c-b978e9bc999c2009-03-03T19:17:27-07:00<p>While the Package tracker is a dandy device, it is far from turn-key.

MAL</p>Skygyver on GPS-08755 - Package TrackerSkygyverurn:uuid:5ededc42-5dcd-ecab-aa3a-c45e629b2fed2008-12-27T07:38:52-07:00<p>Any thoughts on how the sensors would perform under skydiving conditions. 14000 foot elevation 120-180MPH and rapidly changing temperature and humidity. I use the EB-85 with serial data recorder presently but would like to upgrade. I hope to integrate barometric pressure sensor because the GPS looses altitude at pull time. Having a G force indication would be nice also:) I understand there would have to be some reprogramming to the LPC but hopefully this will not be to difficult.<br/>
Thanks in advance.</p>zagGrad on GPS-08755 - Package TrackerzagGradurn:uuid:bff5c2e8-0a27-b999-6810-87db6e07c1932008-12-10T13:05:23-07:00<p>Thanks for the tip! I&rsquo;ll make the code changes and publish the new FW soon.</p>c43948 on GPS-08755 - Package Trackerc43948urn:uuid:573c456c-f49c-47d2-7a3b-d32d163fa8792008-11-26T06:35:18-07:00<p>It looks like that disabling the UART1 interrupt causes the problem on line 131. If interrupt is not disabled on line 131 and re-enabled on line 155 then it works.</p>c43948 on GPS-08755 - Package Trackerc43948urn:uuid:22e07461-4630-138d-ed46-603649634aff2008-11-21T06:11:45-07:00<p>For me the latest v1.1 firmware will cause odd GPS failures.<br/>
The incoming NMEA packets from GPS get corrupted. Some times it receives something like &lsquo;$$PRMS&hellip;&rsquo;. I shortly tried to find out what is happening but i cannot figure out why it gets those extra characters or missing some of them. This does not happen in 1.0 firmware.</p>c43948 on GPS-08755 - Package Trackerc43948urn:uuid:e9c771b5-56e3-3c58-7873-2e92bbe8880e2008-11-12T02:05:54-07:00<p>I think that firmware v1.0 has bug which causes differences between the SCP and SHT temperature values.<br/>
First the SHT humidity and temperature columns have changed places and the temperature is in Fahrenheit.</p>zagGrad on GPS-08755 - Package TrackerzagGradurn:uuid:c96a5704-638f-4b35-2044-90cad01a7bfb2008-09-29T10:09:23-06:00<p>There are unused ADC pins on the LPC2148, however they are not broken out. You would have to solder greenwire directly to the LPC.<br/>
There is easy access to Rx0 and Tx0 which can be reprogrammed to act as I/O or you can use them for serial communication. Pin P0.14 is also easily accesible I/O from the 0.1" header.</p>Unomas on GPS-08755 - Package TrackerUnomasurn:uuid:b0625f36-1751-a234-e5ad-422a4cccb5ca2008-09-29T08:17:11-06:00<p>Are any free/available adc and I/O pins on the board?<br/>
Thank you.</p>MotoZarkov on GPS-08755 - Package TrackerMotoZarkovurn:uuid:af174a4d-1e0a-cb4f-70b6-6391d41fb0e12008-09-25T10:55:21-06:00<p>Great! Now, if we add a cellular module we could possibly call our packages to get REAL tracking updates!</p>
